SFECFICATION forming part of Letters Patent No. 39l,4=62, dated October23, 1888.

Application filed March S), 1888. Serial No. 266,730. (No model.)

To @,Z whom) it 71mg/ concern,.-

Be it known that l, WILLIAM F. DRAPER, of Hopedale, county of Vorcester,State of Massach usetis, have invented an Improvement in Supports forSpinning-Spindles,ofwhich the following description, in connection withthe accompanying drawings,is a specification, like letters on thedrawings representing like parts.

rIhis invention has for its object to improve the bearings of that classof spindle having a sleeve-whirl and wherein all the bearings arelocated below the junction of' the whirl and spindle.

In another application made by me, Serial No. 261,035, I have shown abolster-case provided with a bolster having rollingsurfaces, and in anapplication, Serial No. 266,729, I have shown such a bolster mounted ina bl'l ster-tube loose in the bolster-case. Herein I have shown abolster-case provided with one loose bearing and with one bearing havingrolling-surfaces, both inclosed in a bolster case or support.

My invention consists, essentially, in a bolster case or holder and asleeve-whirl spindle, combined with a divided or compound bolster, onepart of which is mounted loosely in the bolster case or holder, whilethe other part contains a series of rollingsurfaces, such constructionenabling the spindle to be supported in such manner as to vibrate belowits connection with the whirl, to thus accommodate :for uneven loadingand avoid jarring or chattering, the rollingsurfaces reducing thefriction between the parts, thus enabling the spindle to attain highspeed with the expenditure of but little power.

Figure l in vertical section shows a spindle embodying my invention, thespindle being in elevation with the whirl in section. Fig. 2 is asection below the line fr, Fig. 1. Fig. 3 is a section in the line y,Fig. l, looking down. Fig. 4 shows a modified form of my invention withthe spindle broken ofi' above the whirl; Fig. 5, a section below theline m; and Fig. 6 shows the spider by itself.

The rail A, the bolster case or support B, the nut C, and the spindle D,having the sleevewhirl D', are and may be all as usual.

The bolster case or support receives within "it a divided or compoundbolster composed of a tube-like portion, a, in which the spindle belowthe wheel has a running iit, and a portion, as b, having a series ofrollingsurfaces, the said rolling-surfaces being herein shown as shortcylinders held by a spider, as c, (shown separately in Fig. 6,) the saidrolls and spider being common to my application, Serial No. 261,035.

In Fig. l, the slecvelike bolster portion has a collar or flange, a, attop to rest upon the bolster case or support near its upper end, thesaid portion being therein shown assurrounded by an elastic or yieldingpacking orjacket, d. The head or dange of the portion a hasa notch, (seeFig. 7,) which is entered by a lug or projection at the upper end of thebolster case or l support to thus prevent the rotation of the portion a.The outside of the spindle bears against the rolling-surfaces, and thelatter fit the space between the spindle and the inner wall of thebolster case or support..

In Fig. 4, I have shown the portion of the bearing having rollingsurfaces as located near the upper end of the bolster-case rather thannear its lower end, as in Fig. 1, the bearing portion a, bored toreceive and iit the spindle, being restrained from rotation by a pin orprojection, c, the said portieri a in Fig. i being shown as bored forbut part of its length, so as to form a step-bearing.

In this invention the rolls located between the spindle and the rigidcase or support outside ofit, and also within the sleeve-whirl, andsubstantially in the line of the band-pull,lessen friction between thespindle and its surround` ing bearing, while the loose or yieldingportion, as (i, moves to accommodate for the viw bration of the spindleunder an unbalanced load.

Instead of the iibrous packing, cork or metallic springs, or any usualmeans for enabling the bearing to move against an elastic pressure, maybe used without departing from my invention, and would be within thescope of the term elastic packing.77

I claiml. The bolster case or support and the sleevewhirl spindle,combined with a double or compound bearing, consisting of a sleevelikeportion, c, fitting the spindle, and a portion, b, havingrolling-surfaces, both the said IOO bearing portions being locatedWithin the said bolster case or support, substantially as described.

2. The bolster case or support and the sleeve-Whirl spindle, combinedwith a double or compound bearing, consisting of a sleevelike portion,a, fitting the spindle and loose in the said case or support, means toprevent it from rotation with the spindle, and a portion, b, havingrolling-surfaces, both the said bearing portions being located Withinthe said bolster ease or support, substantially as described.

3. The bolster case or support and the sleeve-Whirl spindle, combinedwith a double or compound bearing, consisting of a sleevet5 likeportion, a, fitting the spindle and loose in the said ease or support,and the surrounding elastic or yielding packing, and a portion, b,having rolling-surfaces, both the said bearing portions being locatedWithin the said bol- 2o ster case or support, substantially asdescribed. In testimony whereof I have signed my name to thisspecification in the presence of two subseribing Witnesses.
